Abstract: A display apparatus includes at least one light source per eye, the at least one light source being operable to emit a light beam; at least one beam scanning arrangement per eye, the at least one beam scanning arrangement being configured to direct the light beam towards a projection surface, and to sweep the light beam according to a scanning pattern, the scanning pattern being substantially in a form of a spiral; and a processor configured to control the at least one light source and the at least one beam scanning arrangement to draw at least a first region of an input image over the projection surface, wherein a resolution of the first region of the input image is to vary as a function of an angular distance from a centre of the spiral.

Abstract: An input device including first sensor that measures first sensor data indicative of at least one of: pressure applied to input device, presence or absence of given object in proximity of input device, distance of given object from input device, position and orientation of input device; and processor coupled to first sensor. Processor processes first sensor data to determine state of input device, said state indicating whether or not input device is lying on given object; obtains, from user device, context information pertaining to visual scene being presented to user; and controls input device to operate in first mode of operation or second mode of operation based on said state and context information. Input device acts as computer mouse during first mode of operation and as six-degrees-of-freedom controller during second mode of operation.
